Then there's Para-flinch-fusion, commonly run by Jirachi. With Serene Grace, Water Pulse/Thunder/Iron Head/Calm Mind can be run with great effect. It just takes a long time to set up.
I have tried using thunder wave before but I am always worried about my opponent using substitute or having lum berry. Whats the best way to deal with this?
You need to include liepard as the only non uber fully evolved poke with priority twave
sub
swagger
foul play
twave
can get quite irritating
Liepard doesn't get priority T-Wave... I think you mean Sableye?
You can always rule out the possibility of a Lum Berry if you notice that their health is being restored or reduced through Leftovers and Life Orb, respectfully. Same applies for Choice Scarf if they seem to have an abnormal speed, of course. I've found that Substitute simply requires prediction, though.I have tried using thunder wave before but I am always worried about my opponent using substitute or having lum berry.

Glare is a good strategy, but really it's only viable for NU because every pokemon that gets Glare won't stand a chance in OU (Serperior, Dunsparce, Druddigon, Seviper, Arbok)
Liepard, too. Sure, it can paralyze, but I don't think it's OU status. Sableye has a better typing and a better support movepool, while Whimsicott is faster and also has a better support movepool and typing, and neither of them are in OU. Tornadus and Thundurus-I are in OU and Ubers but that was mainly because of their high offensive prowess, something that Liepard doesn't really have. What makes you think Liepard will be better?
